qeth: recognize vlan devices in layer3 mode
The qeth layer3 driver is notified about IP address changes. Changes concerning qeth driven network interfaces have to be forwarded to the OSA-card. This includes IP addresses of VLAN interfaces with a qeth device as base device. Function qeth_l3_verify_vlan_dev() determines if the net_device of the IP event belongs to a vlan device belonging to a qeth device as real device. This function is broken starting with commit 7ff0bcf676f7ed224ce21b58c7858c8e527068b2 , which means IP addresses of VLAN devices are no longer set at the base qeth device. The patch repairs function qeth_l3_verify_vlan_dev(). Signed-off-by: Ursula Braun <ursula.braun@de.ibm.com> Signed-off-by: Frank Blaschka <frank.blaschka@de.ibm.com> Signed-off-by: David S.
